Grate panel with upright brace structure

ABSTRACT

A grate panel with upright brace structures is provided and characterized by: a plurality of upright brace structures vertically aligned and centrally disposed inside a plurality of side panels of the grate panel, and transversely spaced apart from one another at an appropriate distance; a plurality of reinforcing panels disposed between, and welded to, the upright brace structures; and the plurality of side panels configured to surround the upright brace structures and the reinforcing panels by being welded thereto. Thus, the grate panel is equipped with corrugated upright brace structures to provide such advantages as high-strength support, ease of construction, and low production costs.

BACKGROUND OF THE INVENTION

1. Background of the Invention

The present invention relates to a grate panel with upright bracestructures, and more particularly, to a grate panel equipped essentiallywith a plurality of upright brace structures and thereby capable ofhigh-strength load bearing.

2. Description of the Prior Art

Presently, commercially available grate panels are used in thefollowing: 1. partitions of various plants, such as power generationplants, incinerators, sewage treatment plants, and petrochemical plants;2. platforms and passageways; 3. treads of staircases; 4. cementproducts manufacturing plants; 5. drainage ditch covers for use withdrainage ditches in roads, mass transit railways, bridges, parking lots,parks, urban restructuring areas, and industrial zones; and 6. lockerracks, and fences.

A grate panel is typically composed of load-bearing flat steel barsaligned in the lengthwise direction of the grate panel, and transversebars spaced apart from one another at a particular distance, wherein thebars are welded together by a high-voltage resistance welding machineand go through such processes as cutting, incision, boring, andoveredging to become a finished product that meets customers' needs.

In general, conventional grate panels have their drawbacks, namely highproduction costs, complicated manufacturing processes, and insufficientstructural strength. In view of the drawbacks of the prior art, theinventor of the present invention endeavored to improve the conventionalgrate panels.

SUMMARY OF THE INVENTION

A primary object of the present invention is to provide a grate panelwith upright brace structures. A plurality of upright brace structuresare longitudinally aligned and surrounded by side panels, and aplurality of reinforcing panels are transversely aligned and surroundedby the side panels, wherein the plurality of reinforcing panels aredisposed between the spaced-apart upright brace structures to reinforcethe grate panel with the upright brace structures. Each of the uprightbrace structures is a three-layer structure comprising anupper-positioned reinforcing bar, an intermediate-positioned uprightbrace, and a lower-positioned reinforcing bar, and is vertically alignedinside the side panels. The reinforcing panels connect the corrugateupright braces to one another at appropriately spaced locations, so asto provide structural reinforcement transversely. Accordingly, thepresent invention is applicable to technology-based plants nowadays.

The above and other objects, features and advantages of the inventionwill become apparent from the following detailed description taken withthe accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The present invention provides a grate panel 1 having upright bracestructures.

Referring to FIGS. 1-5, the grate panel 1 with upright brace structurescomprises side panels 1, 2, 3, 4, upright brace structures A1, A2, A3,A4, A5, A6, and reinforcing panels 5, 6, 7. The upright brace structureA1 comprises a reinforcing bar a having a round or flat cross-sectionalshape, an upright brace b having a round or flat cross-sectional shape,and a reinforcing bar c having a round or flat cross-sectional shape.The upright brace b has a projecting leg b1 welded to an end surface ofthe side panel 1, and a flush leg b2 welded to an end surface of theside panel 3. The reinforcing bar a is welded to an upper portion of theupright brace b, while the reinforcing bar c is welded to a lowerportion of the upright brace b. Each of the reinforcing panels 5, 6, 7is rectangular and has an upper portion whose left end surface is weldedto a support bar b11 and whose right end surface is welded to anothersupport bar b21.

Referring to FIG. 4, the reinforcing panel 5 has an upper portion formedwith an insertion hole 52 for securing in position the reinforcing bar ainserted therein. The reinforcing panel 5 further has a lower portionformed with an insertion hole 51 for receiving and securing in positionthe reinforcing bar c in response to insertion of the upright brace b.On the analogy of this, the reinforcing panels 6, 7 bear the aforesaidassembly-related features too. Hence, the upright brace structure A1 isformed by the upper-positioned reinforcing bar a, theintermediate-positioned upright brace b, and the lower-positionedreinforcing bar c welded to one another, and is welded to the sidepanels 1, 2, 3, 4. On the analogy of this, the upright brace structuresA2, A3, A4, A5, A6 bear the aforesaid assembly-related features too.

Table 1 is an embodiment table showing components of the upright bracestructures.

The number of the upright brace structures may be adjusted asappropriate, to meet clients' need.

Embodiment

Side panels 1, 2, 3, 4 are made of iron, so that each of the side panelsis 300 mm or 213 mm long, 25 mm high, and 3 mm thick. Then, an uprightbrace 20, angled at 45° and 19 mm high, is fabricated from astandard-sized iron bar (3 mm in diameter) using a wheeled wavy formgenerating machine. A plurality of reinforcing bars 8 (3 mm in diameter)and a plurality of reinforcing bars 3 (3 mm in diameter) are thenprovided and spot-welded to the upright brace 20 by a spot welder toform the upright brace structure A1. Next, the upright brace structuresA1, A2, A3, A4, A5, A6 and reinforcing panels 5, 6, 7 (22 mm high and 27mm wide) are held together by dampers and welded together by the spotwelder. Afterward, cutting is performed with a cutting apparatus toaccomplish appropriate length, before the upright brace structures andthe reinforcing panels are surrounded with the rectangular side panelsby welding. The finished product is the grate panel 1 with the uprightbrace structures.
